penile-doppler-test

BASICALLY PENILE DOPPLER STUDY IS SONOGRAPHY OF PENIS (USG)

It involves the use of an ultrasound unit to see inside the penis to look at the arteries and veins, and measures the blood flow in and the blood flow out of the penis.

The penile doppler test is pain free.
How is Penile Doppler Test Done?
However, the test does involve an injection into the base of the penis at the start. During this injection, the substance that opens up the arteries, bringing blood into the erection chambers, is introduced into one of the erection chambers. This is the starting event for an erection. It is important to stimulate the blood flow into the penis during this study to see how it might function in real life.
USES OF INTRA PENILE INJECTION
This injection is used for

• diagnosis and treatment of people with – ED – Erectile Dysfunction (Injection is not for every person with ED.) Not only does this injection allow us
• to learn about the workings of the penis, This test gives important information as to the nature of penile function, both in the erect and non-erect state.
  it also
• gives experience as to what this form of therapy is and
• whether the injection will be useful as treatment for a person with Erectile Dysfunction.

Intracavernosal Injection of Vasoactive Substance like Papaverine was the main treatment for Erectile Dysfunction. Even today such injection in the penis is useful for people having Erectile Dysfunction. ED

RISKS OF INJECTION IN PENIS
Intra penile injection is used in people with Erectile

Priapism is a risk associated with intra penile injection.
If this occurs, your physician will have to resolve this issue by using another counteracting substance. Thus it is controllable/manageable.
It is very important that a non-bendable, non-reversible erection be treated within a few hours maximum after it occurs. Failure of letting your physician reverse this prolonged erection could lead to long-term damage and must be avoided.

We hope this information allows you to undergo this study if required in a more relaxed and knowledgeable atmosphere. We will be happy to answer questions. Typically, patients are seen back approximately a week after this to allow the physician ample time to review and interpret the study prior to your follow-up visit.
At the time of your follow-up visit, implications of the study in terms of your treatment options will be discussed.
